Yes, a very helpful article.
What he says about light is very true - midday/afternoon sun is nearly always a disaster; not only does it wash out colours as he describes, it also generates too much contrast and harsh shadows, resulting in detail being obscured.
Early morning light is better, but especially evening sun which just saturates colours wonderfully, as well as being nice and soft.
Very lightly overcast days are more suited to afternoon photography, as the cloud diffuses the sun whilst still allowing warm light to penetrate resulting in better colouring and exposure.
Heavy cloud is rarely useful and often results in stray light getting into the lens, and also overspill from the sky around the fringes of your building.
I'm sure there's a way around this - just have yet to learn it!
